SpruceID

SpruceID lets users control their data across the web. Instead of people signing into platforms, we imagine platforms should sign into people’s data vaults. We implement this pattern into digital wallet ecosystems for governments, enterprises, and blockchains. We believe that architectures that enable individual autonomy in the digital world are necessary for free societies and dynamic economies to thrive.

We release our open-source libraries under the brand SpruceKit, which span foundational building blocks for digital wallets, verifiers, and issuers of digital credentials. Most of our core software is written in Rust, and cross-compiled to different environments as necessary. This ensures we have reduced overhead for common functionality, while taking full advantage of Rust’s efficiency and memory safety on specific platforms.
